“Bose had demonstrated his experimental prowess with homemade instruments employing gunpowder and a bell before British officialdom in the Kolkata Town Hall. He used a homemade 'coherer,' an apparatus he did not seek to patent because he had no interest in making money. Instead, Guglielmo Marconi, who Bose had met in London in 1896, was celebrated for similar work in wireless telegraphy.”
